Redox Steeple

The new steeple on Gunnison Memorial Chapel is installed (remember when it arrived?) and beginning to react with the atmosphere around it. This chemistry, in which copper metal transfers electrons to non-metal atoms from the air to become an ion, is called “reduction-oxidation” chemistry—abbreviated “redox.” Seeing this reaction happen on such a large scale, and produce such an awesome array of colors, is a treat.

    1. Those colors really are the best. It’s one of the reasons I love inorganic chemistry: metals can make any color you can imagine.
